Jens-Christian Fischer has hit email heaven using Zoe, Popfile, and the Opera mail client, M2. I'm working towards a similar setup, but on a Windows box, not Linux. That, of course, will ultimately be my downfall.
I am using Zoe. It has taken some getting used to, it requires a gestalt shift in email theory. But how many times have you wished you could find a certain old email and had to search everywhere for it? GMail promises to end all this by making your email searchable, but you have to have an in - the service hasn't launched yet, and a general willingness to have google steal your privacy. Zoe provides a similar index and search capability.
